Confused if I need a sway control kit

Ok from what I gather I don't "need" a sway control kit for pulling my Coleman Williamsburg with my Chevy HD 2500 Diesel pickup. But we are going to be taking it for it's longest pull yet and going about 6 hours away into the badlands of South Dakota. I guess my question is for less than $50 does it provide security so that you have one less thing to worry about? We can do the wielding at home or where I work so attaching it isn't an issue.

This year I'm into my 2001 Tahoe pulling a 25ft TT with weight dist hitch. This setup is awesome. I'm not even hooking up the sway control bar to it and probably won't bring along. This is 7500 lbs of stuff being pulled north of Duluth, hills and wind and all that fun.

So I don't know if you'd need it on a pup, pulling level and not overloaded. Stay another night camping on President Grant, IMHO

You absolutely don't need it. Even if you buy one, you only need it on one side on a pup. If you do put one on, remember to disconnect it when backing.

The only situation where it may be of benefit is if there were some kind of emergency situation, where someone cut you off or something and you swerve. It would serve to keep the trailer from swaying out of control.

I'm always confused when the sway thing is brought up, and maybe it depends on the type of camper, but I have towed my camper for at least 40K miles and it has never swayed. I suppose you could induce it with grossly improper loading, but more pop ups don't allow for much storage in the rear of the camper.

To those that you say you absolutely don't need an anti-sway friction bar....you are wrong. Coleman/Fleetwood campers made in the late 90's early 2000's had a design flaw that made them sway for little reason. The most notable model was the Bayside Elite commonly referred to as the Swayside. Other models such as the Williamsburg, Niagara and Utah had the same issue although not quite as bad.

I cannot recommend a sway bar either way, it depends on the unit, some sway some don't also how they are loaded makes a difference. You know your PUP and also know if it has a tendency to sway. As Orchid stated if you do be sure and remove it prior to backing up.

If you've towed your trailer at freeway speeds before and not had any sway, then you may not need it - even on a longer tow. If you've felt it swaying before, then a friction bar (anti-sway) is cheap comfort.
We have a Bayside (swayside) and use ours every time we tow - it makes a difference.
